Linux Benchmarking Maildir Delivery on Linux Filesystems
Post date: April 12, 2005, 03:04 Category: Benchmarks Views: 65
Tutorial quote: The goal of this set of benchmarks is to determine which of the leading Linux filesystems (ext2, ext3, ReiserFS, and XFS) offer the best performance when used for accepting maildir deliveries. The resulting system should be a good balance of delivery and retrieval performance under potentially high concurrent filesystem load.
Linux Benchmarking Filesystems
Post date: April 12, 2005, 03:04 Category: Benchmarks Views: 95
Tutorial quote: I recently purchased a Western Digital 250GB/8M/7200RPM drive and wondered which journaling file system I should use. I currently use ext2 on my other, smaller hard drives. Upon reboot or unclean shutdown, e2fsck takes a while on drives only 40 and 60 gigabytes. Therefore I knew using a journaling file system would be my best bet. The question is: which is the best? In order to determine this I used common operations that Linux users may perform on a regular basis instead of using benchmark tools such as Bonnie or Iozone. I wanted a "real life" benchmark analysis. A quick analogy: Just because the Ethernet-Over-Power-Lines may advertise 10mbps (1.25MB/s), in real world tests, peak speed is only 5mbps (625KB/s). This is why I chose to run my own tests versus using hard drive benchmarking tools.
Linux Optimizing Linux filesystems
Post date: April 12, 2005, 03:04 Category: Benchmarks Views: 118
Tutorial quote: Last time we introduced a few common Linux filesystems and examined their features. If you've already installed Linux, your partitions are already set up and configured with particular filesystems, but you may decide you want to modify this configuration. What's the best way to begin?
Debian Filesystems (ext3, reiser, xfs, jfs) comparison on Debian Etch
Post date: April 23, 2006, 04:04 Category: Benchmarks Views: 16
Tutorial quote: There are a lot of Linux filesystems comparisons available but most of them are anecdotal, based on artificial tasks or completed under older kernels. This benchmark essay is based on 11 real-world tasks appropriate for a file server with older generation hardware (Pentium II/III, EIDE hard-drive).
Linux Benchmarking Filesystems Part II
Post date: January 6, 2006, 17:01 Category: Benchmarks Views: 99
Tutorial quote: After the last article was published, I have received more than a dozen requests for a second filesystem benchmark using the 2.6 kernel. Since that time, I have converted entirely to XFS for every Linux machine I use, so I may be a bit bias regarding the XFS filesystem. I tried to keep the hardware roughly the same. Instead of a Western Digital 250GB and Promise ATA/100 controller, I am now am using a Seagate 400GB and Maxtor ATA/133 Promise controller. The physical machine remains the same, there is an additional 664MB of swap and I am now running Debian Etch. In the previous article, I was running Slackware 9.1 with custom compiled filesystem utilities. I've added a small section in the beginning that shows the filesystem creation and mount time, I've also added a graph showing these new benchmarks. After the first round of benchmarks, I received a sleuth of e-mails asking for the raw numbers. The numbers are now included in tables at the end of this e-mail for both the last and current set of benchmarks.
Unix+clones Benchmarking BSD and Linux
Post date: June 18, 2005, 18:06 Category: Benchmarks Views: 99
Tutorial quote: These benchmarks are the result of my scalable network programming research. My interest in this area is to see how scalable and fast network applications can be on standard PC hardware.

I have done most of my research on Linux 2.4, 2.5 and 2.6 kernels using a home-grown distribution I affectionately call "Leanux". I have experimented with several APIs and methods to try and get the most scalability and performance out of a web server. The ultimate goal, however, is to demonstrate scalability by surviving a Slashdotting.
Unix+clones Xen Disk I/O benchmarking: NetBSD dom0 vs Linux dom0
Post date: April 21, 2005, 06:04 Category: Benchmarks Views: 107
Tutorial quote: Xen is a relatively new technology to enable several virtual machines (domU) to run on one computer. The purpose of this article is to determine what operating system (NetBSD or Linux) should be selected as domain 0 (dom0) operating system to get the best performance when running several CPU and disk intensive virtual machines at the same time.
Gentoo EVMS Howto for Gentoo Linux
Post date: April 15, 2005, 00:04 Category: Hardware Views: 453
Tutorial quote: EVMS stands for Enterprise Volume Management System. It's a all-in-one utility written by IBM to manage disk partitions, logical volumes, software RAID and even filesystems.

It does everything from installing the partition table to mounting volumes, fscking and resizing them. It has a plugin mechanism which allow a user to extend EVMS with external drivers.
Linux Linux Filesystems and Partitioning: A Primer
Post date: June 24, 2005, 10:06 Category: System Views: 87
Tutorial quote: We recently to shed some light on Linux, particularly for users unfamiliar with the system. The article received quite a response from around the world and so we will be doing some follow-up articles to teach all those interested, the ins and outs of Linux. In this article, we will be discussing what partitioning is, how to choose a filesystem, how to have Windows and Linux installed on your hard drive at the same time, and more.
BSD Managing Filesystems : fstab
Post date: April 15, 2005, 19:04 Category: System Views: 87
Tutorial quote: Understanding how the BSD filesystem manages disk space is critical to successfully managing a BSD server or workstation. However, this topic is generally overlooked since it is rarely used outside of installation and upgrades. It is also a very simple topic and most people assume you understand how it all works.

This article gives a quick synopsis on filesystem layout and tries to briefly explain how to understand /etc/fstab. The fstab(5) man pages, while good, do little to teach the basics to new sysadmins.
